Authorities fearing terror in the sky turned around a flight to Madrid shortly after it took off from New York when a federal air marshal spotted suspicious wires in a rear lavatory -- but after searching the returned plane they found no suspicious devices.
Port Authority Police, New York City's bomb squad and members of the FBI Joint Terrorist Task Force responded after the flight, Delta 126, returned to the ground at New York's JFK airport.
Passengers were taken off the flight in a "controlled evacuation," sources told ABC News.
However, searchers found no evidence of a bomb.
Authorities had been proceeding with caution and intended to interview the person who found the wires -- apparently one of a team of armed federal air marshals aboard the flight.
Although numerous early reports suggested suspects were in custody, authorities said initially that those reports appeared inaccurate.
